We divide 781361 by 39
The aim is to understand the frequency of 39 in 781361.

Moving on to step 1:
If we divide 7 by 39, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 39

Going ahead to step 2:
The number 39 fits into 78 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 78 from 78, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 39

Let's proceed to step 3:
When dividing 1 by 39, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 39

Let's proceed to step 4:
When dividing 13 by 39, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 200.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 39

Let's proceed to step 5:
39 goes into 136 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 2003.0
Subtracting 117 from 136 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 39

Going ahead to step 6:
39 can be fit into 191 4 times, resulting in a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 20034.0
Subtract 156 from 191 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
39 can be fit into 350 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 20034.8
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 20034.89
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
If we divide 290 by 39, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 20034.897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 20034.8974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 39 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 20034.89743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
When dividing 230 by 39, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 20034.897435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
350 divided by 39 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 20034.8974358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
380 divided by 39 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 20034.89743589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 20034.89743589, and the remainder is 2.9e-08.
